The photo at right shows rigid fiddleneck as seen along Oregon Highway 216 about one mile east of the Deschutes River............Aprtil 19, 2007. Note the scorpioid shape of the inflorescence, acharacteristic of this family.
Rigid fiddleneck is a colorful annual and weed-like wildflower of the intermountain west. Plants have erect, simple to few-branched stems from 10- 100 cm high. The stems are covered with long, spreading, stiff hairs with and undercoat of shorter, softer hairs that point downwards. The leaves are linear to linear-oblong in shape, measuring up to 12 cm long and up to 1 cm wide. The herbage of the leaves is similar to that of the stems, but the hairs may be more appressed. The basal leaves are more numerous and crowded, while those of the stems are more widely spaced and are reduced in size.
The inflorescence consists of a scorpioid spike which uncoils and elongates with age. The 5 sepals are generally equal in size and shape and measure from 5-12 mm long. Individual sepals are linear to linear-lanceolate in shape and measure from 7-10 mm long. The corolla consists of a tube from 5-8 mm long that is barely exserted from the calyx while the limbs or lobes of the corolla range from 1.5-5 mm long. The corolla is typically orange or orange-yellow with reddish markings in the open throat.
